IMPROVEMENT IN' ANIMAL-PVVV-ER. y

The Schedulevreferre'dto in these Letters Patent and making part of the same,

To all whom it may concern.- ,y

'Be it known thatl, JOHN B. HALL, 'of-.Cheshire in the county of' Ontario, and State of New York, have invented a certain new and useful' Improvement in` Dog-Powers; and Ildo hereby declare that the following is a full and exact description of the same, frcferr-ing to the accompanying drawings', in whiohvFigure 1 isa plan of my improved machine.

Figure 2, an elevation of the same. Figure 3 a section, showing the. bearing of the tread-wheel on its standard.

Like letters ofreferenoe indicate corresponding' parts in all ofthe figures.v

' V My improvement belongs to that class in which a revolving tread-wheel bears upon a give moti n to the working-beam.

The invention consists, essentially, in a loose bear ing of the eye of the treni -wheel upon itsstandard, whereby Iany adjustment of the angle of the lsame may be attained, without the use of' a swingingbeam or lever; also, in the same connection, in the employl bar, which not only allows the free adjustment 0f the tread-wheel, but also allows` it to be removed from place by simply takingoli.

1n the drawings- A is the frame, o f any suitable form. B is the tread-wheel, having a loose" eye, b, which fits on an inclined bearing, a, of a standard, secured to friction-gear, to'

the bottom of the frame.

The looseness of the eye-is such as to allow the angle of the tread-wheel to be changed, as desired, to adapt the action to animals ofdilerent weight, as indicatedby .dotted lilies in iig. 3.

In therear of the-tread-wheel is a bearing-roller, b, on which it runs. l

This roller is adjusted up and down, to t the difof ythe tread-wheel, by'its stern or journal passing through any of. a series of holes, d, in the frame.

On one side' of the frame,

at right angles to t', the usual vfriction-gear wheel E rests under the treadwheel, and receives motion therefrom.

On the shaft of' this wheelis situated a crank, F,

.be entirely,

connection with the trend-Y which gives motion to walking-beam D, through the medium of pitman G.

When the crank is at the upper end of' the stroke, the walking-beam stands horizontally, the eii'ect being Asuch that the dasher of the churn can be changed from one hole to another in the end ofI the walking-beam, withoutmakingany verticaladjustment. v

The upper end of bearing a rests in-a socket of a bar, G.

This bar has a vertical adjustment by means'oi mortises, which slide on tenons ol' standards H H of the frame.

lThese tenons have each a series of holes, c c, and a bolt passing through-fthe bar, secures the same in place. This har can The changed to any angle, or can removed 'from place, in which case the tread-wheel can be also removed, bysiinply lifting it ott' from its bearing a.

In this 4invention I disclaim, broadly, the use of a tread-wheeh'and also disclaim simply adjusting the tread-wheel to different angles. v f

This last effect isfshown in a patent already issued, inwhioh the tread-wheel is mounted on a lever, pivoted at one end, while the other moves npand down, to produce the adjustment.

My inventa-ionconsists simply in making a loose eye to the tread-wheel, byv which the adjustment is produced, without other attachments thereto; and in employing, in connection with the same, the adjustable bar C, which is capable, lnot only ofchanging to the different angles, to correspond with the angles of the tread-wheel, but is also entirely removable, to allow the tread-wheel, to lift olf from its bearing.

What I claim as my invention, and desire to se-` cure by Letters Patent, isd- Thearrangement ofthe loose eye'b, bearing a, and removable'and adjustable bar C, when employed in wheel B and friction-wheel i E, in the manner and for the purpose specified.

have hereunto signed my i In witnessv whereof, I name, in the presence of twofsubscribing witnesses.
